Game Plan T-Jack Testosterone Booster Review

Game Plan T-Jack Testosterone Booster Review

Game Plan T-Jack Testosterone Booster First Look:

I have recently put on some good size since lifting heavier and reducing the rep count. For my quite short stature yet fairly naturally broad frame it seems these lower reps and extra heavy weight suits me really well.

I want to secrete more naturally occurring growth hormone though and to so that I need an effective testosterone booster.

I also have my final game of rugby for this season and as a 32 year old this weekend, it is against a solid outfit who know how to play rugby, therefore being as strong as possible and having that extra muscle to absorb and make the hits is imperative.

Therefore, I have come across this supplement which looks like a solid testosterone booster. Nothing gimmicky, just a bold color and confident typeface.


Loquat Leaf Extract (Eriobotrya Japonica) – Finding it very difficult to see any benefit. It has been reported that too much Loquat ingestion can lead to Toxic Myopathy. This is the name given to muscle inflammation and weakness caused by drugs and toxins.

Safed Musli Extract (Chlorophytum Borivilianum) – There is limited evidence for the claims that this raises testosterone levels but in recent testing, a dose of 500mg for 12 weeks increased semen count significantly, there was a slight raise in testosterone but not by a great deal.

Nettle Root – Good for reducing inflammation and an enlarged prostate but has no effect on testosterone.

Maca Root – This Peruvian strain of ginseng is great for lifting libido and mood, however, when it comes to raising testosterone levels it has no effect at all. No significant influences on testosterone in any tested demographic I’m afraid.

Panex (Korean) Ginseng – This form of Ginseng is the most highly researched.

There’s lots of evidence which suggest cognitive function, mood and immunity is increased, however, although there is evidence for better erections and an increase in testosterone production for infertile men.

It can also improve cognitive function.

Coleus forskohlii – Forskolin is a chemical found in the roots of the plant Plectranthus barbatus.

This plant has been used since ancient times to treat heart disorders such as high blood pressure and chest pain (angina), as well as respiratory disorders such as asthma, it can also assist with reducing fat mass in obese people.

However, no reliable scientific information that shows Coleus forskohlii extracts taken by mouth are effective.

BioPerineThe extract of piperine, called BioPerine®  in the patented form, has been clinically tested in the United States.

BioPerine®  significantly enhances the bioavailability of various supplement nutrients through increased absorption.

Tongkat Ali – Eurycoma (LongJack) is a pro-fertility agent and aphrodisiac that appears to have a large body of evidence supporting this role and some evidence suggesting it may be an anti-estrogen and pro-erectile agent.

However, there is a lack of evidence for testosterone boosting in humans, although some very limited evidence in animals.

Vitamin D – D3 is a great Testosterone boosting vitamin that must be taken advantage of to trigger further production of Testosterone in your body.

However, there are two types of Vitamin D. There’s calciferol (vitamin D2) and cholecalciferol (vitamin D3) – we are only interested in cholecalciferol which is D3; this is the type our skin synthesizes from the sun and becomes a hormone which results in the increases in our testosterone.

Research by the US Library of Medicine has shown that testosterone productions are increased with Vitamin D3 supplementation.

Fenugreek Seed (Trigonella Foenum-Graecum) – It is claimed by researchers that fenugreek works to increase testosterone or androgen levels, which decrease as you age.

This is a lot of ingredients, it’s not so much a testosterone booster, it is more like a Nutri Bullet and reading through them all is likely to make you want to put a bullet through your head.

Zinc – An aphrodisiac and Testosterone Booster, but it will only raise testosterone levels if the user is deficient in zinc.

Zinc is also very important for the functioning of the enzyme, hormone, and immune systems.In very high doses, zinc can act as an aromatase inhibitor and reduce estrogen levels. It is also a potent antioxidant and can provide benefits for prostate issues.

Vitamin B6 – Vitamin B6 helps testosterone levels by stimulating androgen (a steroid hormone that acts as a precursor for testosterone) receptors in your body, making your testes produce testosterone.

Vitamin B12 – Studies show that people who are anaemic tend not to have high levels of testosterone because they cannot absorb vitamin B12.

Tribulus – Once again, the old tribulus raises its ugly head.

The problem is that because this has been touted about for so long as a bit of a miracle plant extract used by the mysterious Eastern Bloc Olympic Athletes during the Cold War people have started to believe the hype and it is an easily recognizable ingredient the ill informed will have heard about down the gym.

The issue is that it has not been scientifically proven to raise testosterone levels in any shape or form.

In fact, in studies using elite professional Australian rugby players as participants Tribulus did not produce the large gains in strength or lean muscle mass that many manufacturers claim can be experienced.

Avoid like a medieval plague if you are looking for muscular gainz.

DIM (Diindolylmethane) – Diindolylmethane appears to promote a healthy balance of testosterone in the body and is found in vegetables such as broccoli.

Ginkgo – This appears to help with blood flow and circulation, however, there is no real body of evidence to support these claims.

Horny Goat Weed – Epimedium, the suspected active component of horny goat weed, appears to act as a phosphodiesterase inhibitor, similar to some drugs used for erectile dysfunction.

It does not, however, stimulate testosterone production.


We are instructed to take 4 pills per day.

It is good to have at least 4 tablets but each tablet to be taken over the course of the day to ensure there are no peaks or troughs of the nutrients being utilized by you body.

There’s a daily dose of 2657.02mg which is not quite up there with the best testosterone boosters.


What we have here is  number of solid ingredients such as D3, B6, B12, Zinc, Ginseng, Chlorophytum Borivilianum plus Fenugreek. We can round this off with DIM.

All of these ingredients are known simulators of testosterone production and found in the best testosterone boosters.

There’s also Bioperine which helps with the absorption of these ingredients.

That said, the amounts included are not particularly high.

That’s because there is so many other ingredients too and they’re not necessarily wanted…


There’s Tribulus…that is like boasting about the genital herpes you have not manged to get rid of since your vacation to West Africa.

Then there’s Loquat that appears to inflame muscle and cause weakness which is not ideal when we re trying to increase muscular strength and size.

In total there are 7 ingredients that do not help to directly stimulate testosterone production which is 47% of the total combined number of ingredients.

That means from this testosterone booster, only 53% is effective and that equates to 1212.02mg.

That figure is much less than half of the best testosterone booster available.

Game Plan T-Jack Testosterone Booster Conclusion:

This looks much better than the actual result, a bit like those hot people on Instagram…it’s basically fraud.

While this does include some great ingredients, and there are 9 good ones that are commonly found in excellent products, we are left with 8 ingredients that are shit, 1 of which can have some potentially terrible effects.

Let’s not forget that the 53% only equates to 1212.02mg per day.

Then it misses items which are vital such as Magnesium and D-Aspartic Acid.

Take a look at what works to maximize your workouts.
